The modern AWS‑GUI provides a drag‑and‑drop environment. You can pick components from the element tree and connect them with pipes.
If you simply open an old model in a new version without updating, the software might not know how to interpret the old data, leading to crashes or, worse, silent errors where the simulation runs but gives incorrect results.
Before dragging and dropping components onto the simulation canvas, you must define the global simulation environment. Step 1: Global Properties Open AVL BOOST and create a new project. Navigate to →right arrow Global Properties . Set the Ambient Conditions : Pressure ( pambp sub a m b end-sub ): Default is Temperature ( Tambcap T sub a m b end-sub ): Default is 20∘C20 raised to the composed with power C “AVL BOOST v2024 Tutorial Update: SI Engine Model
: Manages simulation cases, operating points, and global variables.
: Predicts power, torque, fuel consumption, and in-cylinder gas exchange.
: Simulates pressure pulsations and linear acoustics to optimize muffler performance. Element 2: Pipes (P) and Plenums (PL) The
: Specify the RPM ranges (e.g., 1500 RPM) to analyze performance across different loads. Combustion Parameters : Use tools like the AVL BOOST Burn
Recent releases have introduced advanced modeling capabilities beyond traditional ICE simulation:
